Abstract

Projector bulb life is managed to achieve desired performance parameters, such as a maximum life mode or maximum brightness mode, by sensing bulb luminance and applied the sensed luminance with a luminance feedback controller to drive the bulb to achieve the desired performance parameter. For instance, in maximum life mode the luminance feedback controller reduces power applied to the bulb to restrict bulb luminance to a maximum luminance setpoint when greater luminance is available with a newer bulb. In maximum brightness mode, the luminance feedback controller increases power applied to the bulb to increase bulb luminance if the sensor senses luminance below a threshold due bulb wear. Bulb life management improves project image illumination to display information in a variety of projector types, including digital mirror devices and liquid crystal displays.

Description

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] The present invention relates in general to the field of information display, and more particularly relates to a system and method for managing projector bulb life.

[0003] 2. Description of the Related Art

[0004] As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and / or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how...

Embodiment Construction

[0016]Projector bulb life management enhances the display of information, such as that generated by an information handling system, by illuminating an image having the information with a luminance designed to achieve desired bulb performance parameters, such as maximized life or maximized brightness over the life of a bulb. For purposes of this disclosure, an information handling system may include any instrumentality or aggregate of instrumentalities operable to compute, classify, process, transmit, receive, retrieve, originate, switch, store, display, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an information handling system may be a personal computer, a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. The information handling system may include random access memory (RAM), one or more p...
